[adhyt_blank]

hi everyone ... I tried to grow willughbeia sarawakensis, baccaurea macrocarpa and macrocarpa edulis from seed. They grow but now the tip of the leaves began to dry up, what should I do?

Do you apply fertilizer, Is it in full or part sun

Yes I use manure mixed with soil (soil taken from under the bamboo trees), they are only briefly exposed to the sun in the morning.

I think its the manure, they look like their getting too much nitrogen, usually tropicals like low nitrogen and higher potassium and mid phosphorus. I would plant them in the soil without manure, add broken up leaves and sticks mixed in with the dirt, and let the water your going to use for the plants sit out for a week or longer to allow algae to build up in the water. Should do the trick.

apparently stung by the sun.

The yellowing of these leaves is too much nitrogen, it could have also been burned by sun too.
